Use this option to map an instrument to a part and its corresponding parameters for taking measurements for the Gauge R & R study. You can also view the number of trials done for a parameter along with the date and time of the last trial. Once all trials for all parameters have been completed then that study is not displayed on this screen.
The local machine no. (i.e. Station No.) shall be considered by default for mapping details for an instrument.
Click Add to add a new record. Select Instrument Code from the drop down list displayed from the Instrument master. Study Date displays the current date. Select appropriate date not less than the current date, if required. Select Part Code from the drop down list displayed from the Part master. Select Parameter Code from the drop down list. This list contains only those parameters which have not been mapped to the selected instrument code, study date, part code and local machine.
Enter the Master Value. Specify the Reading Mode – whether Automatic or Manual. Enter Tolerance and Process Variation. At least one of these two fields must be entered.
Select Decimals, No. Of Parts, No. Of Operators and Trials Per Operator from the drop down lists. Their default values are 0, 10, 2, and 2 respectively.
Click Save to save the record. You can map only as many parameters as are specified for the interface code of the instrument.
Once a parameter has been mapped for an instrument, No. Of Parts, No. Of Operators and Trials Per Operator are set for all subsequent parameters.
Use Pp Value, LSL Value and USL Value to calculate GRR value using Pp method.
Click Modify to make changes. You can modify Decimals, Reading Mode, Master Value, No. Of Parts, No. Of Operators, Trials per Operator, Tolerance, Process Variation and Study Date only if trials have not begun for the selected Instrument Code, Part code and Parameter code. If some trials have been taken for the mapped part and parameter then you can modify only Decimals and Reading Mode. If you change No. Of Parts, No. Of Operators or Trials Per Operator for a parameter, the same change is made for all other parameters mapped to that instrument code.
Click Measure if you wish to go to the Gauge R & R Measurement screen to record readings.
Click Delete to delete a record. You can delete a record for a Local Machine only if trials have not begun for it. For deleting a record, you must specify the Instrument Code, Study Date, Part Code and its corresponding Parameter by selecting them from the respective drop down lists.
